No, not for sure. But Swedish national TV broadcaster SVT streamed the current ongoing live event "Den stora älgvandringen" (the great moose migration) flawlessly during the Solar Flares to the internet. You can see some aurora borealis in live stream around 0:29 am today. For them it did not seemed to be a huge problem. SVT also use Arelion/Twelve99 as ISP btw, the same company that also SE uses for its EU servers.
